I have a mortise lock and recently the dead bolt part will slide out without turning the cylinder lock. This will cause the bolt to be stucked on the dummy side of the double door and the door won't open.
I took it apart and found the problem. There is a spring/hinge thingie that is broken...here is a picture of where it should be:

If you look at the full size image I have drawn a red line where the hinge used to be connected and now it is broken. I then took the hinge apart and this is what it looks like:

Is there a replacement part for this? Is this a genetic part I can order? I put everything back then took the entire mortise to a local locksmith and described the problem to him and he said I need to replace the entire mortise which will be a special order and $135.00. I said it is only a hinge and he told me the mortise lock are made to be replaced in whole and not in part and I should not even try to fix it if I take it apart I will just "hurt" the internal mechanism. Really?
